Solar-Roofs, Inc. may bring a much-needed boost to Halley City's economy. The company, known by some as a cutthroat business, has recently developed solar roof panels that are 25 percent more efficient than panels made by competing companies. In order to keep up with increasing consumer demand, Solar-Roofs, Inc. plans to hire more than 2500 new employees within the next six months.

The company is the leader in its field but didn't get there without its share of struggles. During the 1990s, Solar-Roofs was a subsidiary of Sol-E Industries, a British global-energy company with headquarters in London. CEOs from both companies didn't agree on a solution that would take Solar-Roof out of the slump it had been in for over three years. In the end, Rob Miller, Solar-Roof's President, quit after Sol-E laid off one-third of Solar-Roofs' workforce. Eventually, Solar-Roofs was sold to PBB Solar.

Under the new parent company, Rob Miller agreed to come back to Solar Roofs, Inc. as the new CEO. Miller implemented new processes that turned his company into a gold mine within two years. With a new source of funding, Solar-Roofs began manufacturing new panels using the newest technologies available. Their sales increased 200 percent within the first three months.
